Preheat oven to 350° F and spray the bottom and sides of a springform pan. Set aside.
Using a mixer, cream the dairy-free margarine and granulated sugar together until light and fluffy. Add the applesauce and vanilla and combine until thoroughly mixed.
In a medium bowl, combine the flour, baking powder and salt. Add the flour mixture to the margarine mixture, alternating with the non-dairy milk. Combine but don't overmix.
Stir in the dairy-free chocolate chips and pour into the springform pan. Place the sliced strawberries, cut side down. Bake 45-50 minutes until it is lightly browned on top and toothpick comes out clean. Let cool before slicing. Sprinkle the top with powdered sugar and serve.
